• Teem• For all your raster data needs

• MatlabInterface• .mat files <-> SCIRun

Converters

• Convert between human-editable text (e.g. CVRTI .pts, .dat files) and SCIRun Persistent objects

• See examples in SCIRunData/convert-examples/• Each converter gives you usage info if invoked without

arguments: dmw stitch% TextToHexVolField

Usage: TextToHexVolField pts hexes HexVolMesh [-noPtsCount] [-noElementsCount] [-oneBasedIndexing] [-binOutput] [debug]

This program will read in a .pts (specifying the x/y/z coords of each point, one per line, entries separated by white space, file can have an optional one line header specifying number of points... and if it doesn't, you have to use the -noPtsCount command-line argument) and a .hex file (specifying i/j/k/l/m/n/o/p indices for each hex, also one per line, again with an optional one line header (use -noElementsCount if it's not there). The hex entries are assumed to be zero-based, unless you specify -oneBasedIndexing. And the SCIRun output file is written in ASCII, unless you specify -binOutput.

• Soon, plug-ins for Readers / Writers

Teem

• Make sure “unu” is in your path (it’s in /some/path/Thirdparty/…./bin/)

• For import:• unu make -h -i <input> -s <nx ny nz> …• NrrdReader module

• For export• NrrdWriter• unu data
